It might not be for everyone, but if you've got an iPhone, iPad, or are just heavily invested in iTunes, AirPlay should be on your checklist for your next speaker purchase — and the Logitech UE Air Speaker ($400) offers exactly that. Packed inside the sleek black body are dual tweeters and dual subwoofers, as well as a pop-out iPad/iPhone/iPod dock that helps with effortless setup, streamlined top-mounted controls, and a 3.5mm input for other audio devices — cable not included.
